Mozilla really does not understand UX, in my book. An example: when it asks me if I want it to remember my login for a site. There is no option to tell it to never try to remember anything for any site. I have to go through various levels of settings to get to (or even bloody find in the first place) the setting that would let me turn off that annoying nagging bullcrap for ever.

(Ditto the "reader view" or whatever that hell junk crap is called.)
